Check out this tweak, I got about 10 more fps and faster processing from it.
By default Windows 7 uses different timers in the CPU to calculate stuff. HPET is the newest and best of these timers, but because of default combination of timers it takes longer time for CPU to keep up all the timers and sync between them. Forcing Windows to use HPET only improves performance and leads to greater FPS.

Download this windows timer tester and test your system before and then after the tweak below.

Steps to enable this tweak:

1. Enable HPET in BIOS. If you have HPET option in BIOS then your hardware can support HPET.

The usefulness of this tweak depends on hardware setup. However, what appears to be universal is that you will see a performance increase if HTEP is either the only timer activated or entirely deactivated. Which of these are better for you depends, as previously stated, on what kind of hardware you have and you should experiment (if you know what you're doing, of course) to see which one suits your computer best.
